Honestly, I'm not wild about Beringer so I'll pass on any of those offers. No offense.
I know there are a lot of mixers out there so please don't call... unless it's free

I am also looking for a splitter snake. I guess that's what it's called. One side goes to the FOH mixer and the other goes to the Monitor mixer.
I plan on shopping around but will be buying it within two weeks.
Thank you in advance,
Dan
